SHUTTLE.

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed June 21, 19GB. Serial Nc- 266.199.

To LEZ whom t may concern:

Be it known that I, EDUARD Hnnzre, a citizen of the United States, and aresident of West Hoboken, Hudson county, State of New Jersey, haveinvented certain new and useful Improvements in Shuttles, of which thefollowing is a specification.

My invention relates to shuttles such as are used in looms; and itconsists in the novel construction and arrangement of parts, as will behereinafter described, the features of novelty being pointed out in theappended claims.

Reference is to be had to the accompanying drawings, in which- Figure 1is a face view of a shuttle constructed accordin to my invention. Fig. 2is a detail sections. view of the spool-support, and Fig. 3 is anelevation thereof.

A is the body of the shuttle, provided with the usual rack B and havingarecess or chamber C. A second recess or chamber D is arranged withinthe chamber C and contains two pivoted sprin -arms E' and F,providedwith eyelets E an F and constituting a tension device. This part of theshuttle may be of any ordinary construction and part of the resentinvention. support or ro Gr bottom C of the chamber and is provided witha sleeve H, which in the present instance is somewhat shorter than therod G, A coil-spring I is arranged around this sleeve and has its oneend secured thereto at J and its other end fastened at K, the coils ofsaid spring I becoming wider apart as they near t e free end of thesleeve H. The object of this construction will become a parent from thedescription hereinafter. spool L is provided with a pin M arid carriesthe thread which passes from the s ool L down throu h the rod G, throughdiie eyelets E and of the s ringarm E and F, and through eyelets theshuttle. An arm Q, pivoted at R, is arranged to swing across the freeend of the rod G, the free end of said arm Q1 entering a notch S in thebody of this shutt e when said arm is in position over the su port G. Inoperation the spool L- is place on the support G, the pin M engaging theupper coil of the s ring L. The said spool 1s then turned, t e coils ofthe springs acting as a screw-thread, serving to lock the pin M and Ahollow forms no extends u Wardly from the and an opening P out of withit the spool in position on the support. The end of the spool does notengage the bottom C of the chamber (l when the spool is in position onthe su iport, thus doing away with any friction etween the end of thespool and the bottom of the chamber during any rotation of the spoolwhich might take place as la pull is exerted on the thread from anycause. It is to be understood that the thread leaves the spool in thesame direction in which the spool is turned in lookin@ it to thesupport, so that any pull on the `thread will fasten the spool on thesupport more securely, it being understood that the spool L does notturn as the thread leaves it. The arm Q serves as an additional means toprevent the spool Jfrom leaving the su port.

With my device I obtain a sim le and efiicient device Jfor securing thespoo in position in the shuttle, which locking device is Hexible orresilient, and thus also serves as a device for equalizing the tensionon the thread during the operation of weaving. By having the coils ofthe spring wider apart as the near the i'ree end of the sieeve H a quielocking of the spool with the support is secured, the coils of thespring acting as a steep screw-thread.

Various rnodications may be made without departing from the nature of myinvention.

I claim and desire to secure by Letters Patent# 1. In a shuttle, asupport, a coil-spring arranged around said support, and a spool adaptedto be carried by said support and provided with a pin arran ed to engagesaid coil-s ring to lock the spoo to the support.

2. In a shuttle, a support, a spool ada ted to be carried b saidsupport, and a resi ient member for loc ing said spool to the su port.

3. In a shuttle, a support, a spool a apted to be carried by said suport, and provided with locking means, an a coil-s ring engaging saidlocking means for loc ing said spool to the support.

4. In a shuttle, a support, a sleeve on said support, a coils ringaround said sleeve, a spool adapted to e carried by said support, and aprojection on said spool arranged to engage said coil-spring to lock thespool to the support.

5. In a shuttle, a support, a coil-spring around said support, the coilsof said spring IOO beoomin Wider apart as they near the free end of t esu port, a s ool, arranged to be slipped over tiie free on of saidsupport and provided with a projection adapted to enter 5 into enagement with the coil-spring et the point W ere the coils are Widestapart, to look the spool to the support.

In testimony whereof I have signed this specification in the presence oftwo subsorib ing witnesses.
